Scientists reveal how dividing cells precisely trigger spindle formation‎

During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes split correctly into the two cells. Spindle fibers—complex machinery responsible for choreographing this dance—form from each end of the cell and push and pull the chromosomes through the process. But scientists still do not fully understand how cells control where and when the spindle fibers themselves form.
